Phone dying @ 20%

    Hi all,

    5S has been powering off around the 20% mark ... Plug it in then and comes on straight away back @ 20%

    Never had an iphone that acted like that

    Any suggestions?

    Worth trying to calibrate the battery using this method:

    Failing that, it might be new battery time.

    Usually means the battery has failed. You can ring Apple to run a diagnostic and they can confirm this.

    Failed After 14 months? poor ...
    Will Apple do a diagnostic test if it's out of warranty?

    Will try recalibration later

    Got on to Apple ... They say battery looks ok ... Gonna have to set it up as a new phone.

    If that doesn't work they say it will be covered under the 2 year eu law. (1 year warranty is up)

    Good customer care from Apple (so far)

    I had the same thing immediately after upgrading to 8.1.2. None of the above have worked so far so next up is restoring it. I have AppleCare so it's not a big deal really.

    Speaking from experience, Apple have the best customer service. Will look after you 100%

    I got a refurbished iPhone 5 from Apple about 8 months ago as my 5 was faulty. In the last 2 months, the battery has gone to crap. Dying at any point under about 15%.
    Took it out of the charger 9 hours ago, has had 2 hours use today, only one call though. Most of the use was Twitter and Whatsapp. It's down to 11%. It the last 10 minutes of use it has gone down 24%!!!!

    Battery has always been crap on my iP5, luck to get the whole day out of it even if it's just sitting in my pocket.

    I noticed recently that it tends to just shut down randomly if the battery is in single digit territory. Sometimes at 2%, other times at 6 or 7%. Once it was at 4% and I plugged it in, battery immediately jumped to 14%, plugged it out straight away and it stayed at 14%.

    Checked that site before, my phone isn't one of the defect ones, so I've always just assumed the battery technology on the iPhone 5 was crap to begin with.

    It's a work phone, so I'm not concerned with having it working perfectly, I'm just going to bother the purchasing guy to blag me an upgrade. :D

    Update: Did a restore - set up as new phone.

    Battery seems better ... but getting sudden drops ..example jump from 8% - 2% in a second.

    Got back onto Apple ... they are going to replace it, and they are even waiving the fee for the express pickup service (sending out replacement first).

    Great service ... phone is out of warranty (15 months old).
